it's a great joy when someone articulates something you've thought about but never put into words. I should not have to do legwork to figure out whether your game is a sequel to a game I've never heard of, or just a game with an unnecessarily long title!
this is a mild, unserious take but i think with few exceptions you shouldn't name your very first game in a series [Thing]: [Subtitle]. you should just have to name it [Thing] and then if it does well and you make a second one you can start adding subtitles.
